Dual Condense (DCT) patented technology:
1/ “Water condenser” mode: The heat recovery system condenses all the refrigerant gas using the cold water from the water tank. It recovers all the heat rejected by the cooling unit. The electronic board adjusts the pump speed to heat up the water at 55°C in one pass whatever the ambiant temperature.
2/ “Desuperheating” mode: when all the water has been preheated, the electronic regulation switches the fans on.The heat recovery system continues heating up the water (gas desuperheating); water can reach a temperature of 65 / 70°C in summer.
The system runs within the operating envelope of the compressors (pressure and in compressor temperature); Water condensation improves the compressor efficiency in summer and avoids high pressure cut-off. The HP safety pressure sensor restarts ventilation in case of water circuit dysfunction: priority is given to refrigeration.
